数据开放共享的分布式自治安全监管机制理论与关键技术研究

分布式自治安全监管机制,是大数据开放共享中的研究热点，具有重要理论意义和应用价值。首先，探索如何利用去中心价值网络，来激励大数据开放共享中的价值流动，同时保障开放共享过程中的隐私。课题将提出智能合约的安全分析模型，基于智能合约的数据交换和访问控制模型，基于智能合约和交易混合模式隐私保护模型等。然后，为提高能源互联网结算的安全性，本课题还将利用区块链技术，为能源互联网的相关各方，提供一个激励与合作机制。最后，根据量子信息的特性，着重研究量子密码、区块链技术与物联网的结合，从而健全大数据安全的保障体系，围绕量子与区块链技术，从安全性角度出发，拟设计出基于格密码的数字签名方案，以有效抵抗量子计算攻击。本课题的理论成果将为随后的实用化提供科学依据。本课题成果，将促进数据开放共享的分布式自治安全监管，为我国在此领域的研究，特别是为实现贵州的大数据国家战略，赢得一定的发展先机。

The theory and key technology of distributed autonomous security supervision are the research hotspots in the open sharing of big data, which have important research significance. Firstly, we explore the use of de-centralized value network to stimulate the value flow in the open sharing of big data, while ensuring the privacy protection in the process of open sharing. This project will propose security analysis model of smart contract, data exchange and access control model based on smart contract, privacy protection model based on mixed mode of smart contract and transaction, etc. Then, in order to improve the security of energy internet transaction, this project uses blockchain technology to design a traceable and authenticated key agreement scheme for distributed application and settlement of energy internet. Finally, according to the characteristics of quantum information, combined with blockchain technology and distributed Internet of Things data, a new digital signature scheme based on lattice cryptography is proposed. It can effectively resist quantum computing attacks and improve the security system of big data. The theoretical research results of this project provide scientific basis for the future practicality. This project plays a very important role in promoting the research of distributed autonomous security supervision theory and key technologies for data open sharing, which can win a certain development opportunity for our country in this field of scientific research,especially for the realization of guizhou's national strategy of big data.
